ToaruOS v1.99.6

ToaruOS v1.99.6

What's New in v1.99.6?

• CPU time tracking has been implemented, which finally brings a top utility and related libc functions.
• The network stack has been expanded and the e1000 NIC driver has been rewritten. UDP sockets may now be bound, transmit throughput and reliability has been improved, and an interface to ICMP has been added (alongside a ping utility).
• Performance in the package manager has been improved, and there are new packages: doom and mupdf.
• The Julia set renderer has been rewritten with new palettes and exploration tools.
• The EFI loader has been recovered, with new options.
• Various improvements have been made to the panel, image viewer application, and file browser.
• New assets for ToaruOS 2.0, including a new wallpaper and logo.
• The terminal and file browser text input bar now display an I-beam cursor.
• Rudimentary support has been added for timezones, with automatic detection at startup if networking is available.

What is ToaruOS?

ToaruOS is a hobbyist, educational operating system for x86-64 PCs, focused primarily on use in virtual machines. It provides a Unix-like environment, complete with a graphical desktop interface, shared libraries, feature-rich terminal emulator, and support for running, GCC, Quake, and several other ports. The core of ToaruOS, provided by the CD images in this release, is built completely from scratch. The bootloader, kernel, drivers, C standard library, and userspace applications are all original software created by the authors, as are the graphical assets.

Who wrote ToaruOS?

ToaruOS is primarily written by a single maintainer, with several contributions from others. A complete list of contributors is available from AUTHORS.

Running ToaruOS

It is recommended that you run ToaruOS in a virtual machine / emulator, for maximum compatibility. ToaruOS's driver support is limited, and running on real "bare metal", while possible, does not provide the most complete experience of the OS's capabilities except on very particular hardware. ToaruOS is regularly tested in VirtualBox, QEMU, and VMWare Player, and can be successfully booted (with poor performance) in Bochs. ToaruOS is intended to run from a live CD, though it is possible to install to a hard disk. Additional details on running ToaruOS in different virtual machines is available from the README.

Release Files

image.iso is the standard build of ToaruOS, built by the Github Actions CI workflow. It uses ToaruOS's native bootloaders and should work in most virtual machines using BIOS and possibly EFI.

Known Issues

• The SMP scheduler is known to have performance issues.
• Several utilities, libc functions, and hardware drivers are missing functionality.
• There are many known security issues with ToaruOS. You should not use ToaruOS in a production environment - it is a hobby project, not a production operating system. If you find security issues in ToaruOS and would like to responsibly report them, please file a regular issue report here on GitHub.
